The answer depends on what your goal is.
Laundry soap that I make is intentionally "lye heavy" so it strips oils from the clothing. ( no superfat or lye discount)
Soap for washing skin has a certain percentage ( I use 4 to 6 percent) of unsaponified oils ( superfat or lye discount) so it does less stripping of oils.
Then there's the "numbers"..Hardness: Cleansing: “Conditioning”: Bubbly: Creamy: Lasting:
Some calculators do not use the "lasting" number.
All these are calculated based on the fatty acid profiles of the oils you choose to use. Play with using different percentages of the same oils like: Lard, Palm, olive, rice bran, coconut etc and watch what the numbers do. Please note that soap does NOT "condition" so that number is misleading. Soapcalc is a good place to start while learning and there is a link to it in the Beginner's section.
Clear as mud , right?
